Researched by Industrial Info Resources (Sugar Land, Texas)--Spanish energy company Repsol (Madrid) announced last week that it has started commercial operations at its Outpost solar farm in Webb County, Texas, in the far south of the state near Laredo and the Mexican border.
Construction on the Outpost solar farm began in late 2024, with Primoris Renewable Energy (Aurora, Colorado) acting as engineering, procurement and construction (EPC) firm. In less than two years, Primoris managed to situate and energize more than 1.3 million Siemens solar panels. The 629-megawatt (MW) project is now connected to the Electric Reliability Council of Texas (ERCOT) grid, which serves most of the state. Subscribers to Industrial Info's Global Market Intelligence (GMI) Project Database can learn more by viewing the project report.
The Outpost facility joins other Repsol solar developments in Texas, including some that are under construction. The company reports that its renewable capacity in Texas, both established and in development, stands at 2,681 MW. Established plants include the 233-MW Sandy Branch solar in Wharton County (see plant profile) and the 632-MW Frye plant in the Texas Panhandle (see plant profile), while the company has more than 1,000 MW of solar projects under construction in the state.
Those under-construction projects include the Pinnington project in Jack County and the Pecan Prairie development in Leon County. The Pinnington project is located near Bryson, about 75 miles northwest of Fort Worth. Construction kicked off in 2024, installing First Solar (Tempe, Arizona) panels across the 14,000 acres of available land. The 825-MW project is expected to be completed next year, but that may not be the end of the site's development. Repsol has proposed plans to add battery energy storage to the site, although this remains some years away and, depending on the schedule and whether it occurs at all, may not be connected to the grid until 2028.
The Pecan Prairie solar project is more central to the state, located between Austin and Dallas, roughly 120 miles from each city. The facility is being constructed in two phases, both of which are underway, and the plant's full 595 MW of power is expected to be online early next year.

While Repsol's primary U.S. destination to this point has been Texas, the company is developing projects elsewhere in the country. Most notable is the Heritage Prairie project in Illinois, which Repsol is developing with Pattern Energy (San Francisco, California). In addition to a 204-MW solar facility, the companies will add 600 MW of wind power through the addition of 62 GE Vernova (Cambridge, Massachusetts) wind turbines. Construction on both the wind and solar portions is expected to begin next year, putting the facility on track to begin generating power by mid-2028.

Expected to begin construction toward the end of this year or early next year is Repsol's Rail Tie wind project in Albany County, Wyoming. This project will feature 150 turbines, each rated at 3.3 MW, to provide nearly 500 MW of energy at peak generation. However, the project has had legal challenges brought against it in regard to wildlife and may face another challenge: its location near the Ames Monument National Historic Landmark, which marks what was once the highest point of the Union Pacific Railroad.
Under the Biden administration, the U.S. Bureau of Land Management (BLM) established a two-mile buffer zone between the monument and the turbines, but this may not prove adequate under the second term of U.S. President Donald Trump. The Trump administration last month repealed permissions to the 1,000-MW Lava Ridge Windfarm in neighboring Idaho in part because the nine miles separating the nearest turbines from the Minidoka National Historic Site, where Japanese-Americans were interned during World War II, was deemed inadequate. While the Rail Tie Windfarm could potentially begin generating power by 2028, Repsol could face further permitting challenges.
